description Porcupine Ray Overview

The porcupine ray (Urogymnus asperrimus) is a species of stingray found in coastal waters throughout the Indo-Pacific region. It is uniquely characterized by its complete lack of a venomous tail spine. Instead, this ray relies on passive defense, possessing numerous sharp, thorny denticles covering its entire dorsal surface. It typically inhabits coral reefs, estuaries, and shallow sandy flats where it forages for benthic invertebrates.
